Counting Atoms, Naming, and Bonding

Counting Atoms, Naming, and BondingSothis is chemistry.Classification of ElementsUses position on the periodic chart (dictated by how the element acts) to tell what the element isWe already did this with the coloring of the chart

Valence electronsThe number of electrons in the outermost shell Tells a bit about how it will reactCan tell by position on the periodic chartCounting AtomsSo two elements combined makes a compound. There is bonding involved.You need to COUNT the number of each type of atom in a compoundYou can tell this from the formula

Some more examplesMagnesium fluoride(MgF)One atom of MagnesiumTwo atoms of FluorineSodium chloride (NaCl)One atom of SodiumOne atom of ChlorineYou can name compounds based on what they are made of Mono - 1Di - 2Tri - 3Tetra - 4Penta - 5Hexa - 6Hepta - 7Octa - 8Nona - 9Deca - 10

Some examplesNitrogen oxideDinitrogen oxideNitrogen dioxideDinitrogen pentoxideDinitrogen trioxideSo lets try counting a fewHOLiFKSH2SO4CH4C8H10N4O2Another complication2 KS3 HO4 HSO

Yet another wrench3 Ca(NO3)22 Fe(NO3)25 BaSO4
